[U-Boot-Users] warning unable to open inital console

Wed Jul 30 09:09:09 CEST 2008

Hello all,

I have mpc8313erdb board and trying to boot kernel from NAND flash ...
Everything is fine but finally it stops and says;
**
*Warning: unable to open an initial console.
Kernel panic - not syncing: No init found.  Try passing init= option to
kernel*
**
following is the log of the booting sequence;

I tried with init=linuxrc (symbolic link to bin/busybox) but still says the
same error as mentioned above ...

What argument I should pass init= xxxx ...

Kindly please acknowledge ... thank you ...

Kind Regards,

Vijay Nikam
